Title: Manufacture of isocyclic compounds
IPC: C07C305/10

Abstract: Products stated to have wetting, foaming, dispersing, and cleansing properties are obtained by treating with a polybasic mineral acid or an anhydride or halide thereof or with amidosulphonic acid a compound having the formula R.O.X.Y wherein R is a mononuclear aromatic or hydroaromatic residue containing at least one aliphatic hydrocarbon substituent with at least three carbon atoms, X is an aliphatic residue whose chain is interrupted by at least one ether oxygen atom and Y is a hydroxy group in end position or approximately end position in X.  The products may be used in association with other washing agents, e.g. phosphoric acid salts or bleaching agents or with common salt or sodium sulphate.  In examples, the following ethers are treated with chlorsulphonic acid: dodecylphenyltriglycolether, octylphenyldiglycolether, decylcyclohexyltriglycolether and alkylphenyl (or cresyl) polyglycol ethers obtained by treatment with ethyleneoxide, the condensation products of phenol (or cresol) with chlorinated petroleum hydrocarbons or a chlorinated paraffin fraction prepared by hydrogenating coal or by treatment with ethylene oxide, the condensation product of phenol with lauric acid, after reduction.  In further examples octylphenyldiglycolether is treated with phosphoruspentoxide and octylphenyltriglycol ether with pyrophosphoric acid.  The use of amylcresyldiglycolether, nonylphenylpolyoxypropylether and octadecylphenylpentaoxypropylether is mentioned.  The ethers used as starting material may also be made by the process described in Specification 470,181 from the mononuclear aromatic and hydroaromatic hydroxy compounds having a nuclear aliphatic hydrocarbon residue with at least three carbon atoms and alkylene oxides.  A sample has been furnished under Sect. 2(5) of the sodium salt of a sulphuric acid ester prepared from isododecylphenylpentaglycol ether by means of amidosulphonic acid.ALSO:Products stated to have dispersing properties are obtained by treating with a polybasic mineral acid or an anhydride or halide thereof or with amidosulphonic acid, a compound having the formula R.O.X.Y wherein R is a mononuclear aromatic or hydroaromatic residue containing at least one aliphatic hydrocarbon substituent with at least three carbon atoms, X is an aliphatic residue whose chain is interrupted by at least one ether oxygen atom and Y is a hydroxy group in end position or approximately end position in X.
